Colloidal Quasi‐2D Cs2AgBiBr6 Double Perovskite Nanosheets: Synthesis and Application as High‐Performance Photodetectors

open access: yesSmall, EarlyView.
Layered quasi‐2D Cs2AgBiBr6 nanosheets, with large lateral dimensions of up to 1.4 µm, which are only a few nanometers thick, were synthesized as a result of systematic investigation of the roles of ligands and reaction temperature. The nanosheets were used to develop high‐performance photodetectors, yielding detectivity in the order of 1012 Jones with

Exploration of Copper Halide Linear‐Array Detector Prototype for Security Checks

open access: yesSmall, EarlyView.
Mn‐doped Cs3Cu2I5 is demonstrated as a highly promising scintillator for X‐ray imaging, featuring high light yield, a low detection limit, and negligible afterglow. A linear‐array detector prototype based on the Mn‐doped Cs3Cu2I5 delivers a spatial resolution of 1.1 lp/mm in food‐safety and security inspections, marking a significant advance in the ...

A Bibliometric Review of the INCOSE's Model‐Based Systems Engineering Roadmap

open access: yesSystems Engineering, EarlyView.
ABSTRACT Over the past decade, model‐based systems engineering (MBSE) has gained attention as an approach for managing system complexity, offering a shift from a document‐based to a model‐based approach. The International Council on Systems Engineering (INCOSE) sparked increasing interest when it introduced MBSE and its roadmap as part of its systems ...
